Method for extracting volatile oil from geotrichum candidum through fermentation of burdock by utilizing supercritical extraction method and application

Abstract

The invention discloses a method for extracting volatile oil from geotrichum candidum through the fermentation of burdock by utilizing a supercritical extraction method and an application, belonging to the technical field of tobacco spice extraction. The method of the invention adopts the geotrichum candidum to ferment and degrade the grease components harmful to the sensory quality of tobacco, carries out the supercritical carbon dioxide extraction to obtain the burdock volatile oil after the fermentation, has the advantages of effective measures and obvious technical effects, and is simple in operation and easy in implementation, and the extracted volatile oil has the advantages of high yield and good quality. The obtained burdock volatile oil contains more fragrant components same or similar to the tobacco, can be coordinated with the initial fragrance of the tobacco when being added to tobacco shreds, and has the effect of enriching and coordinating the tobacco fragrance, promoting the quality of the tobacco fragrance and reducing the simulation. Particularly, the micro-molecular organic acid generated from the grease components after degradation can effectively enhance the tobacco fragrance and reduces the simulation.
